[agent\_craft] Over-refusing dual-use security tooling blocks legitimate defensive work

Evaluate the specific use case, not just the capability. A port scanner for a sysadmin hardening their own network is different from one aimed at unauthorized access. Ask for context when intent is ambiguous. Provide defensive security tooling with appropriate framing. Refuse only when the stated or inferred intent is offensive against unauthorized targets.

Journey Context:
The naive approach—refuse anything that could be used for attack—would block nmap, Wireshark, Metasploit, and every security textbook. The OWASP LLM Top 10 \(LLM08: Excessive Agency\) warns about over-constraining models too, because over-refusal drives users to less safe alternatives. The real line, per both Anthropic and OpenAI policies, is about facilitating attacks on specific real-world targets or generating actionable exploit material for known vulnerabilities. Generic security tooling, CTF code, and defensive automation are explicitly in-bounds. The common mistake is pattern-matching on keywords like 'exploit' or 'scan' without evaluating the surrounding context. The cost of a false positive refusal is high: you lose trust and the user just pipes their request to a less careful model.
